A computerized job bank would be most effective in reducing _____ unemployment.

A) seasonal
B) frictional
C) cyclical
D) structural

A computerized job bank would be most effective in reducing frictional unemployment, which is caused by individuals who are in between jobs or are entering the workforce for the first time. The job bank could help match job seekers with job openings and reduce the search time for both parties. Seasonal unemployment is caused by changes in demand for certain products or services during different seasons. Cyclical unemployment is caused by changes in the business cycle, such as recessions or booms. Structural unemployment is caused by changes in the structure of the economy, such as technological advancements or industry shifts. A job bank would not be as effective in reducing these types of unemployment.
